About Pietersite
Formula:
SiO2
A variety of Chalcedony
Chalcedony with embedded fibers of amphibole minerals with varying degrees of alteration. Blue-gray, brown and yellow colors. The fibers cause a chatoyancy similar to that seen in tiger's eye, but tiger's eye is not made of chalcedony, it is macrocrystalline quartz.
